What is that? A generator car made from an FM short hood?
A transfer cab that used to be used in Roanoke Terminal.
Did you notice the Hobby Horse on top?
My interest was piqued, so, I did a little digging and with some help I found that N&W 6, before being turned into a quasi-transfer cab actually started life as a "Poling Car".
If you can't cypher the drawing, this is kind of what it would have looked like with the poling apparatus in place.
Standing on the ground holding a big pole while the engine butted up against it to pole a car was a dangerous way to move cars around. owever, this car might make it a tad bit safer.
Somewhere along the way N&W 6 lost its ability to "pole" and original shed (cupola?), later to gain the FM short hood to somewhat protect the crew from the elements.
